For example, when the source 40 is a halogen lamp, the heating source may have a reflective plate, which is set in a direction opposite to the direction in which the light moves toward the target of the coating. Optical uniformity. when . When a 6-Hai reflective plate is placed, it can be directed toward the coating target by reflecting light emitted in a direction opposite to the direction of the coating target, thereby effectively supplying heat energy. The heating source is 4〇. In order to uniformly and simultaneously supply thermal energy to the entire range of the coating target 1 ,, the coating material is applied thereto. The heating source 4G may be the entire range corresponding to the coating target 〇 . For example, gp 士关1 α - J, as shown in Figure 1, can be provided with a single heating source 40 overlapping the entire coating target. In another example, a plurality of heating sources can be arranged to overlap the entire coating target 丨0. For example, the heating source 40 can comprise a flat plate having the same shape as the coating target 10f. And at least a portion of the heating source 40, ie, the flat plate, may be substantially parallel to the target of the coating: as in the xy plane, and may overlap with the coating target 10, Overlap. The exception is the movable coating component 33, i.e., 10 201114500, such as a bottom surface of the entire coating target 1 ,, also gp will be derived from the heating; the coating target 10 is originally. Therefore, the flat plate exposed to the heating source 40 faces the surface of the coating target 10, so that the thermal energy of 4 〇 can be applied to the coating material of the coating target substantially simultaneously and uniformly. It can be uniformly dried into a substantially uniform thin layer. Conversely, when the thermal energy is supplied to the coating material in a manner of π a , unevenly, that is, sequentially, the temperature supplied by the thermal energy may change, thereby changing the characteristics of the coating material. Therefore, it may be difficult to form a thin layer of coating material having a uniform sentence quality. (4) When the heating source is not separated from the stage, the stage may be adversely affected by thermal energy, and the substrate supporting the coating material is not between the parts, such as the front end and the rear end. The difference can be seen in the month b. Thus the movement of the coating liquid may cause the coating to collapse. In addition, the substrate cannot be heated to 1 由于 due to conventional techniques.匚 or higher to increase the accuracy of the stage, so it may be difficult to heat the coating liquid without causing liquid flow. The heating source 40 is movably disposed in a vertical direction (the z-axis direction u toward the (four) stage 20. Therefore, it is possible to prevent or significantly reduce the interference caused by the heating source 4 to the movement of the coating member 30. The source 40 can be moved in a vertical direction so that there is no need to provide a non-movable heating source at a fixed distance from the coating target and the coated component to avoid elongating the need to heat the coating target at a greater distance. Time and at the same time improve the accuracy of the device. In other words, when the coating component 3 is subjected to a coating treatment, the heating source 40 can be significantly separated from the coating target. When the coating treatment 201114500 is completed 'The heating source 40 can be lowered toward the stage 20 in the Z-axis direction, and heat energy is supplied to the coating target 10 for drying treatment. Then, when the drying process is completed, the heating source can be along Z. The axial direction rises to be separated from the stage 20. On which the coating target 10 is a sealed step 2, the coating member 30 and the heating source 40 can be disposed in a chamber 5 This The stage 2 can be disposed at a lower portion of the chamber 50, and the heating source 4 can be disposed at a higher portion of the chamber 5〇. This embodiment illustrates the coating. The component 30 is a movable member relative to the step 2 to apply the coating material to the coating target, although other embodiments are not excluded. For example, the coating member 3 can be relatively The substrate 20 is fixed, and the coating target is movable to apply the coating: to the mobile coating. The target '丨〇., a coating according to an exemplary embodiment. The apparatus may include the coating rod 10' on which the step 20 is placed; the coating member 30 is movable in the processing direction (X-axis direction) by which the coating material is applied to the coating rod 10; and the heating source 40' which supplies thermal energy to the coating material on the coating target 10' and when the coating treatment is completed, it is available for drying, ie, liquefied coating material. A heating device can provide a substantially uniform hook, i.e., a thin layer coating having a substantially uniform thickness and/or features. In the traditional method, when the coating and dry material treatment of the material is applied, the coating is applied to the processing, that is, the mechanical arm is used in a coating 5 and a separate drying material. Between the R and the R-transports - the coated coating material, the thin layer of the layer material may be deformed, ie, 12 201114500 has a non-uniform thickness. That is, due to the applied state The carrier is carried into the desiccation: this: the substrate of the arm of the beta undried arm, ie, the target of the coating target = the mechanical degree of the machine may be changed, the substrate may be carried by the substrate The external force generated during the process and/or the centripetal force generated by the rotation of the substrate may seriously cause the thin layer thickness on the substrate to be difficult to form a high quality thin layer. Therefore, the composition of the coating device according to the present exemplary embodiment is thin.

In other words, the same equipment as the coating can be treated by the temperature at which the liquefied coating material does not flow, i.e., about 100 〇c to about 200 〇c, and thus a portion of the solvent can be removed. The heat treatment, that is, drying the liquefied coating material, is performed to avoid deformation of the coating material 4 layer according to the exemplary embodiment. The heating temperature according to the exemplary embodiment may be lower than the temperature of a conventional individual drying apparatus, that is, such as about 25 〇〇c or more, whereby a reaction occurs between elements in the materials contained therein to obtain some characteristics. This is to avoid or significantly reduce the high thermal effects on the composition of the coating material as compared to conventional separate coating/drying equipment. It should be noted that due to the high temperatures applied to conventional drying equipment, it may not be applied to conventional coating equipment 'so the coating target within the conventional coating equipment can be carried to the drying equipment to pass, for example, additional drying program. That is, as shown in FIG. 3, in the coating apparatus 1 according to the exemplary embodiment, an organic material may be applied to the coating target 1 以 to constitute an organic layer 12 of an OLED 11 13 201114500 » The OLED 11 may contain A first electrode layer 13, the organic layer 12 and a second electrode layer 14' may be sequentially deposited on the coating target 10', that is, a substrate 10. The substrate 10 can be any substrate suitable for the OLED, i.e., any suitable substrate having sufficient strength to support the 〇LED π. The substrate 1〇 may be composed of a soft material or a hard material depending on the application. For example, the substrate 10 may comprise glass, quartz, polypropylene, polyethylene terephthalate 8 曰 polycarbonate, polymethacrylate, polymethyl methacrylate, polymethyl acrylate, polyester, etc. One or more. When light emitted from the emissive layer of the organic layer 12 passes through the substrate 10, the substrate 10 may be composed of a transparent material. However, when the light emitted from the emission layer of the organic layer 12 passes through the side opposite to the substrate 1 ’, the substrate 1 不受 is not limited to the transparent material. . The organic layer 12 may be formed by a single layer structure containing an emission layer, or a structure having two or more thin layers including the emission layer. In the organic layer (1), in addition to the emission layer, a charge injection layer such as a hole injection layer or an electron injection layer, or a charge transport layer such as a hole transport layer or an electron transport layer may be formed. It is noted that the emissive layer of the organic layer 12 may be composed of an organic material and may be composed of the coating apparatus... discussed above with reference to FIG. 1A2. However, other thin layers, such as organic layers, can be formed by the same method. The liquefied organic material may be liquefied by the material supply device, wherein the material for the luminescent layer of the component 3 is dissolved in a solvent and supplied to the injection 201114500. For example, the organic layer 12 may contain any suitable luminescent organic material. And may include, for example, a toner emitting material, a metal composite emitting material, a polymer emitting material, and the like. In addition, an additive such as a dopant medium or the like is added to improve the emission efficiency and the emission wavelength, and the solvent may be, for example, toluene, trichloromethane, amp; Taste, Oxygen Park, etc. When the substrate 1G is disposed on the stage 2 (), the coating member % can be moved in the "processing direction of the sea (X-axis direction) so as to be emitted from the inside of the coating head 33a through the nozzle 3 a certain amount of organic material, whereby the organic material is applied to the substrate 1G, after the application of the organic material, the heating source 40 can supply thermal energy to the substrate 1 on which the organic material is applied. 0, and the liquefied organic material may be dried to constitute the organic layer 12. Here, the temperature increased by the heating source 40 may range from about 1 〇〇〇c to about 2 〇〇〇c depending on the solvent type of the organic material. Therefore, the organic material dried in the coating apparatus 1 according to the exemplary embodiment can be sufficiently cured and can have a substantially uniform thickness. It can be seen from the description that since the coating material is dried in a coating apparatus, deformation of the thickness of the thin layer can be prevented, that is, as a substrate is conventionally carried from a coating apparatus to a drying. The flow of material caused by the equipment. Further, since the substrate is not in contact with the heating source, it is possible to avoid thermal deformation of the substrate during heating. In addition, since the heating source is not provided in the stage, the deformation of the stage can be avoided, and the accuracy of the accuracy can not be adversely affected. At the same time, since the coating material can be heated at a temperature of about 〇〇〇c or above, sufficient heat energy 15 201114500 can be supplied to the coating material.
